Efficacy Of Clodronate 200 Mg/4 Ml I.M. Solution With 1% Lidocaine Every Other Week Vs Clodronate 100 Mg/3,3ml I.M. Solution With 1% Lidocaine Once-Week In A 1-Year Treatment Period Of Women With Postmenopausal Osteoporosis

• Status: Completed

Summary

Clodronic acid 100 mg/3,3 ml is used to prevent and treat postmenopausal osteoporosis.

The intramuscular formulation, which is given at a dose of 100 mg every 7 o 14 days, is at least as effective as daily oral therapy and appears more effective than intermittent intravenous treatment. Intramuscular clodronic acid in particular has also been associated with improvements in back pain. The drug is well tolerated, with no deleterious effects on bone mineralization, and use of parenteral therapy eliminates the risk of gastrointestinal adverse effects that may be seen in patients receiving oral bisphosphonates therapy.

In order to simplify the therapeutic dosing regimen, reducing the number of administrations per month, and therefore increase adherence to bisphosphonates therapy of the patient, a new formulation of disodium clodronic acid containing 200 mg/4 mL for i.m. administration has been developed. Lidocaine in this new formulation, as local anaesthetic, is maintained at the same concentration as in the 100 mg clodronic acid formulation.

The pharmacokinetics and tolerability of the intramuscular formulation of clodronic acid 200 mg in comparison to the marketed formulation clodronic acid 100 mg was evaluated in healthy post-menopausal volunteers. Two formulations were similar in terms of amount and rate of clodronic acid urinary excretion and in terms of safety profile.
